Hi Julia,
I saw your post and wanted to share some info. as just as concerned as you on section 3’s content!
I agree that the portion of the new exam pertaining to section D is vague at best. I reached out to CLARB both by email, and then by phone, but was still given a non-specific description. The person I spoke with said the best way she could describe the test content was as ‘testing our knowledge of conceptual design through design development. I asked what this meant in terms of materials, fasteners, etc., and she said anything construction related would really be the focus of section 4.
I know this doesn’t clarify much, but it may help with ruling out some of the more detail-oriented D material. I’ll be sure to share any other information I can find out – would be great to know where Stormwater will be tested!
